Since the occupation of an abandoned space for housing purpose in 2014 by around 90 migrants, the housing use "legalization" of an abandoned private building, was reached in 2018. Urban stakeholders have been involved and activated, the space has been regenerated with a multidisciplinary approach and housing comanagement and small informal economic activities have been set. It was possible by the simultaneous presence of inhabitants and works and by people’s self-maintenance. Specific pieces of rules were identified and articulated in a sort of technical and legal tool consistent with the current legal framework. The Italian planning system is defined as urbanism (EC, 1997) and conformative (Janin Rivolin, 2008, 2017): in response to a local community social need, not foreseen by the existing plan, the proponent of an eventual response to that need could not propose a solution, not included in the existing plan, although responding to a territorial development objective. The concept of interventions' predetermination within conformative systems does not include the promotion of voluntary territorial development proposals, approved because of their contribution to development objectives. Predetermined interventions prevail on development objectives, so if territorial needs are not foreseen by the plan, responding by parts is necessary. In this case, the intervention was divided into parts attributable to preordained determinations, assembling a technical and juridical construct, resulting in an overlap of normative fragments belonging to the existing legislative apparatus. Nevertheless, this ad-hoc juxtaposition cannot ensure the automatic realization of further interventions on the same site. In conclusion, although the inflexibility of conformative urbanism, the production of a sort of new rule, has permitted the realization of an "unexpected" project.entemporary collective housinglegalizationself-productionco-managementArticle1559-1568
